SEAMlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 531,814, dated January1 1895.

Applica i n filed February 28, 1893. Renewed November 24, 1894. SerialNo. 52 (N0 model-l To all whom it may concern:

, Be it known that I, GUSTAV FRIEDRICH Vo- GEL, a subject of the King ofSaxony and of the German Emperor, residing in the town of Cells, nearAue, in the Kingdom of Saxony, German Empire, have invented certain newand useful Improvements in Scanning-Machines, of which the-following isa specification, reference being had therein to the accompanyingdrawings.

This invention relates to a novel construction in seaming machines,adapted for use more particularly in rigidly seaming together the endsof a bent tin plate to form a canbody, the object being to provide amachine of this kind that is simple and durable in construction andefficient in operation.

The invention consists in the features of construction and combinationsof parts hereinafter fully described and specifically claimed.

In the accompanying drawings illustrating my invention,Figure 1 is aside elevation of a seaming machine constructed in accordance with myinvention. Fig. 2 is a front end ole vation of the lower portion of themachine, partly broken away. Fig. 3 is a top plan view of the upper endportion of the machine. Fig. a is a bottom plan view of the die-head onan enlarged scale. Figs. 5, 6, 7, 8 and 9 are detail views partly inside elevation and in vertical section, of the die-head and plateholder, illustrating such parts in the different positions they willassume during the seaming operation.

Referring now to said drawings, 1 indicates the base of the frame of themachine having the standard 2 which is bifurcated at its upper end 3 asshown. The plate holder a consists of a cylindrical body secured at oneend to the standard 2 of the machine (Figs. 1 and 2). Mounted upon thestandard 2 and in front of the bifurcated portion 3 is an upright dovetailed guide 4 that enters a dovetailed groove in the die-head 5 andserves to guide the same. The die-head 5 can be moved up and down by alever g pivoted at one end between the bifurcated portion 3 of thestandard and having a slot 6 therein that receives a pin 7 carried bylugs 8 on the upper end of the diehead 5. A spring is secured at one endto the standard and bears against the lower face of the lever g andserves to lift the same and also the die-head 5, while pressure on theouter end of the lever g serves to depress the die-head. The die I) issecured to the lower end of the die-head 5 in a familiar manner as by aset screw 5. The sides of the die are inclined or tapered as shown.

The plate holder 66 is provided with an inclined recess 9 to receive theseaming die cl, and against one of the inclined sides of the dieb is adovetail groove 10 to receive the scaming die-plate c (Fig. at). The died and dieplate 0 stand with their operating edges opposite each otherand their movements are so oh that they remain parallel with each other.A guide plate 6 is movabl y secured against the die-plate c by twoscrewsf that pass through slots 11 in the guide plate e.

The die-plate c is operated by a lever 72. that is pivoted at one endupon a pivot 12 inclined at rightangles to the inclination of thedieplate 0 and provided with a slot 13 that receives the pin 0 on thedie-plate c. The cylindrically bent tin plate for a can body is placedwith its edge it against the projecting edge of guide plate e, and theother cdge got the tin plate is placed in and against the noseprojection 14 of die (Z (Fig. 5). Now we move the die-plate c downwardby pressing upon lever h, whereby the edge or of the tin plate is bentover the nose projection ll of die d to form a rectangular ledge, asshown in Fig. 6. Now by moving the die-plate 0 still farther downward,the edge got the tin plate is bent to form an up-bent ledge. At the sametime the lever g is operated to move the die 17 downward, so that thetwo ledges remain in the relative grasping position Fig 7. Until now thenose projection lei of die 61 resisted the pressure of die-plate 0,because the die (1 rests with its lower beveled or notched edge 15 uponthe spindle i. This spindle i is passed concentrically through cylinder0!. and by means of a crank Z it can be rotated (Fig. 2).

The spindle i is flattened on its upper side as at 16, and when rotateduntil the flattened surface comes parallel with die d, said die (Z thesaid recess 9, and while the'die 2) changes its position from that shownby Fig. 8 to that shown by Fig. 9 the ledges of the tin plate are bentone over the other and itpressesthe thus formedseam into the seaminggroove it, made in the die b or plate holder 0,, but conven of die platewill move from right to left in Figs. 5 to 9, and the seam formedthereby will be compressed between thedie b and the cylin'der' or plateholder. After the die I) has been lifted and the can body withdrawn, thesprings m will lift the die (1 to its first position when the spindlescan be turned also to its former position as shown by Fig. 5.

It will be understood, of course, that although I have describedthe'difierent movements of the various parts as being accomplished byhand power, yet suitable mechanism can be made for automaticallyoperating the different parts.

1 1 I claim as my invention- 1. In a seaming machine the combinationsubstantially as hereinbefore set forth with the frame carrying acylindrical plate holder a provided with a die cl movable thereintangentially, of a die I) mounted also upon the frame of the machine andmovable toward and away from the plate holder or radially moving saiddie I; and die plate 0 independently of each other, substantially asdescribed,

Owing to the angular directions'of the movable within a tangential,recess inthe said plate holder at and having a lower notched edge 15, aspring located within said recess to hold said die at the outer limit ofits movement, a spindle i mounted upon the frame of the machine andpassing through an opening in'the plate holder at and engaging thenotched end of said die at, said spindle t being provided with aflattened side 16 to permit the passage of said die d, and a die I) anda die plate 0 mounted upon the frame of the machine and provided withdevices for operating the same, substantially as described.

4:. In a seaming machine the combination substantially as hereinbeforeset forth with the frame of 'a plate holder a'having a movable diednormally projecting beyond the periphery of said plate holder andprovided with a nose or projection 145 at its upper edge, 7 v

a die 12 provided with a die plate c, a guide normally projecting belowthe lower edge of the same, and devicesfor operating said die b and dieplate 0, substantially as described.

5. In a seaming machine the combination substantially as hereinbeforeset forth with the frame having a plate holder or rigidly securedthereto and provided with a die at movable with relation to said plateholder, devices for holding said die rigid with the plate holder, of adie b mounted upon theframe of plate e movably secured to said die plate0, and
